To a/ZZ whom it mag/concern.-

Beit known that I, HANS MAERKER, engineer, a subject of the Kin of Prussia, German Emperor, residing at iesbaden, Leberberg 8, in the Kingdom of Prussia, German Empire, have invented new and useful Improvements in Tires for Wheels, of which the ollowing is a specification.

This invention has for its object a tire for the Wheels of bicycles, motor-cycles, and motorcars.

In the Wheel-tires hitherto em elasticity, which is a necessary con ition for a stead leasant running or traveling, is obtainedv by india-rubber or neumatic tires, which, however, have many rawbacks, owing damaged. In addition loyed the and tear, which renders them very expensive.

The object of the present application removes these drawbacks and affords byreason of its ver easy removability and cheapness, combine with practically unlimited durability, the best substitute for pneumatic tires.

The principal advantage, as compared with other elastic or resilient tires, becomes evident more particularly in long tours. If, for instance any dama e by glass, stones, nails, and the like is foun in a pneumatic tire, the latter requires a troublesome repairing, absorbing a long time. Even this is frequently out oi the question, and then the air-tube and outer cover has to be entirely replaced. In this improved wheel-tire, on the other hand, only the dama ed steel segment need be replaced by a resli one, which may easily be carried in the pocket by any cyclist or motorist.

The metal pieces employed in these improved Wheel-tires are made of cast steel, alu minium, and other like metals or their alloys. lAn arrangement of this character is shown as an example and diagrammaticallyin the accompanying drawinfrs, in whichv Figure 1 is a vertica section on the line a b of F1g. 2, and, Fi 2 a vertical section seen from the side, whi e Fig. 3 shows the arrangement applied to a bicycle.

he arrangement of this improved wheeltire is substantially asfollows: On the inner rim F, held fast b the spokes, a s rin W is mounted, the en s a: y of which' ol with small play in two yokes b a steel segment L,

in which a linoleuni or other suitably-composed insertion U' is introduced for the purpose of deadening the noise. A rectangular pin V is passed through the block B of the spring W, which pin is attached to the rim F by means of a nut locked by a pin, so that the spring W is connected with the rim F as a rigid whole. The rectangular pin is secured a ainst turning by means of a washer-disk S, W ich is placed over the projecting part of the pin and has two egs m and m, which engage in suitable hoes in the rim. Two leather disks R R2 are )laced between the nut M and the washer' b, respectively, and the rim F to prevent wear and to deaden noise.

Having now described my invention, what I wish to secure by Letters Patent of the United States isf 1. In an elastic tire for wheels, in which the elastic tire proper is composed of a plurality of separate segn'ients and of a like number of carriage-springs, each of which has its ends connected 4with one of said segments, and its middle portion secured to the inner or rigid tire of the wheel, the combination with each segment and its appurtenant spring, of yokes b b xed to the inner side of the segment, and adapted to receive the ends of the spring, these ends being rebent outside of said yokes, and means adapted to prevent the spring with its segment from turning out of the lane of the wheel, said means being appliedp to the middle portion of the said spring, for the purpose as described..

2. In an elastic tire for wheels, in which the elastic tire proper is composed of a plurality of separate scgmen ts and of a like number of carriage-springs, each ot which has its ends connected with one of said segments, and its middle portion secured to the inner or rigid tire of the wheel, the combination with each segment and its appurtenant spring, of yokes b b iixed to the inne`sj'dje of the segment, and adapted to receive, the ends of the spring, these ends being rebentoutsi de of the yokes; a hole of rectangular shape provided in said s ring; a bolt V having part of its shaft of t e same section located in said hole; another hole provided in the inner rim and adapted to receive the screw-threaded portion of the bolt-shaft a Washer-disk S located IOO between the inner rim and the spring anct Inwitness whereof I have hereunto set my taking over the rectangular prtion of (said hand in presence of two witnesses.

bolt pins m m secured to sai Washe'r-V isk y l and taking into asutably-provded portono'f HANS 5 the inner rim, and a nut M screwed upon the Witnesses? nwardl -proj eating end of the said bolt, sub- EMIL BUERWALD,
